Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an automatic warehouse including a shelf having a compartment storage space and an access device provided on the front side of the shelf.

2. Description of the Related Art Conventionally, as an automatic warehouse as described above, for example, the structure shown in Japanese Patent Laid-Open No. 62-295807 has been provided.
That is, a crane supported and guided by guide wheels on the floor through traveling drive wheels is provided, and the upper end of the crane is guided by the ceiling guide rail.

Problems to be Solved by the Invention According to the above conventional type, due to the existence of the ceiling-side guide rails, the length of the crane post or the like must be designed for each beam height (shelf height) of the equipment, Further, a member for supporting the ceiling side guide rail is required, and the overall design, manufacture and construction become complicated. Further, when the upper end (roller or the like) of the post is slidably contacted with the ceiling-side guide rail, dust generated due to abrasion or the like floats and falls, thereby polluting the surrounding area.

An object of the present invention is to provide a warehouse facility in which a ceiling-side guide rail can be omitted and a stable work can be expected at all times.

Means for Solving the Problems In order to achieve the above object, an automatic warehouse of the present invention has a shelf having a compartment storage space, and a loading / unloading device provided on the front side of the shelf, and the loading / unloading device is a wheel. By the traveling machine body supported and guided by the floor-side rails via the and lateral deviation prevention rollers, the support frame which is erected from the traveling machine body and whose upper portion is not guided, and the lifting platform which is guided by the support frame and has the loading / unloading tool. The center of the weight of the loading / unloading device is deviated to one side with respect to the center of support by the floor side rail, and a guide rail is provided on the floor side at this one side and is supported and guided by this guide rail. A guide roller is provided on the traveling body side.

According to the configuration of the present invention, the running of the loading / unloading device can be performed by supporting the wheels on the upper surface of the floor-side rail and abutting the lateral shift prevention rollers on both side surfaces of the floor-side rail. At that time, the center of self-weight is deviated to one side with respect to the center of support and the upper part of the support frame is not guided, so the loading / unloading device tends to lean to one side. Since the rollers are received and guided by the guide rails on the floor side, the loading / unloading device travels on a fixed route in a stable posture.

Embodiment One embodiment of the present invention will be described below with reference to the drawings.

Reference numeral 1 denotes a storage shelf having a plurality of compartment storage spaces 2 in the vertical and horizontal directions, which comprises an outer frame body 3 and post bodies 4 arranged in the outer frame body 3 at predetermined intervals in the horizontal direction. The post body 4 has a plurality of receiving portions 4A vertically protruding from both side surfaces in the vertical direction, and these receiving portions 4A form the partitioned storage space 2. Reference numeral 5 denotes a case (article) that can be stored in the compartment storage space 2.

The storage shelves 1 configured as described above are arranged in a pair with the passage 10 placed, and the passage 10 side is the front surface. This passage 10
Inside, there is provided a loading / unloading device 12 capable of traveling on a fixed path 11 along the front surface of the storage shelf 1.

That is, a floor side rail 13 is laid in the passage 10, and a traveling machine body 15 is placed on the floor side rail 13 via a plurality of wheels 14, and the traveling machine body 15 side is contacted with both side surfaces of the floor side rail 13. A lateral deviation prevention roller 16 that can be freely contacted is provided. A supporting frame 17 whose upper part is not guided is erected from the traveling machine body 15, and an elevating table 18 supported and guided by the supporting frame 17 is provided, and an elevating drive device 19 and a traveling drive device 20 are provided.
It is provided on the 15 side. On the lifting table 18, a loading / unloading tool 22 that is rotatable about a vertical axis 21 and movable in the left-right direction.
Is provided.

The gravity center G of the loading / unloading device 12 is offset to one side with respect to the support center C by the floor side rail 13. This deviation can be performed, for example, by disposing both drive devices 19 and 20 on one side, or by moving the lift 18 to one side with respect to the support frame 17. And on one side, while providing a channel-shaped guide rail 25 whose inside is open on the floor side,
A guide roller 26 fitted and supported by the guide rail 25 is attached to one side surface of the traveling machine body 15 via a roller shaft 27.

A cargo handling area 6 is provided outside the end of the storage rack 1.

 Next, the operation of the above embodiment will be described.

When carrying out the warehousing operation, first, the loading / unloading device 12 is caused to travel and the elevating table 18 is moved up and down so that the elevating table 18 faces the intended compartment storage space 2. At this time, the loading / unloading tool 22 has the lengthwise direction in the left-right direction and is at a slightly lower level than the intended compartment storage space 2. In this state, the loading / unloading tool 22 is projected to move, and the desired compartment storage space 2
Is plunged below. Next, by raising the elevating table 18 a little, the case 5 supported by the receiving portion 4A is taken out and put in.
Lift at 22. Then, the loading / unloading tool 22 that supports the case 5 is stored in the lift table 18.

By performing the reverse operation to the above, the case 5 supported by the loading / unloading tool 22 can be stored in the intended compartment storage space 2.

In addition, the case 5 can be transferred to and from the separate handling place 6 by running the loading / unloading device 12 on the fixed path 11 so that the loading / unloading device 22 faces the loading / unloading place 6 and performing the same operation as described above.

A case 5 is provided between one storage rack 1 and the other loading / unloading area 6.
When the case 5 is loaded or unloaded, or when the case 5 is transferred between both storage shelves 1, the orientation of the loading / unloading tool 22 is changed. That is, as shown by the solid line in FIG.
After turning 22 around the vertical axis 21 and moving it as indicated by the imaginary line (a), it turns to the opposite side as indicated by the imaginary line (b).

The above-described running of the loading / unloading device 12 can be performed by supporting the wheels 14 on the upper surface of the floor side rail 13 and abutting the lateral deviation prevention rollers 16 on both side surfaces of the floor side rail 13. At that time, since the center of gravity G is displaced to one side with respect to the support center C and the upper portion of the support frame 17 is not guided, the loading / unloading device 12 tends to lean to one side. Since the guide roller 26 is received and guided by the guide rail 25 on the floor side, the loading / unloading device 12 travels on the fixed path 11 in a stable posture.

EFFECTS OF THE INVENTION According to the present invention having the above-described configuration, the ceiling-side guide rail is omitted, and the guide structure is provided on the floor side, so that the length design of the support frame and the like is performed without being restricted by the beam height of the equipment. In addition to being able to eliminate the need for complicated support members that support the ceiling side guide rails, the overall design, production,
Can be easily constructed. Further, since dust generated due to abrasion or the like in the guide structure falls to the floor side near the guide structure, it does not float or drop on the article or the loading / unloading device, and the cleaning of the surrounding area can be promoted.
